Powell joined the club two years ago to join Danny Johnson's backroom staff as first team coach, and last season took on the role of head of player development, working closely with the Ashton United Development Squad.
He revealed that it was a tough decision to leave but having had previous managerial experience at Ashton Athletic he felt that this was a good opportunity for him to get back into management at a good standard of the game.
Ashtonutd.com would like to thank Dave for all his hard work whilst at the club and wish him well in his new role at Valerie Park.
